About Strongyloides ratti

The nematode Strongyloides ratti, or rat threadworm, is a minute common gastro-intestinal parasite of the rat. S. ratti is a laboratory analogue of the human parasite, S. stercoralis.

Genome Assembly & Annotation


The reference genome was assembled by the Parasite Genomic group at the Wellcome Trust Sanger Institute, in collaboration with Mark Viney (University of Bristol), using a combination of capillary, 454 and Illumina paired-end sequence and genetic map data, and improved using bespoke manual and automated tools (WTSI Strongyloididae Nematode Genomes Project, Hunt et al. (2016)).


The gene predictions were made by the Parasite Genomics group at the Wellcome Trust Sanger Institute as part of the Strongyloididae Nematode Genomes Project, Hunt et al. (2016). An in-house automatic pipeline (based around AUGUSTUS plus MAKER) was used to generate first-pass gene models, and this was followed by a round of targeted manual curation of selected gene families.
